#4367 Describe step-by-step application of TRIZ 40 Principles

Applying the TRIZ (Theory of Inventive Problem Solving) 40 Principles is most effective when used as a systematic process to overcome a specific technical contradiction. Rather than simply browsing the list for inspiration, the following structured approach ensures you are solving the right problem.

1. Identify the Administrative Contradiction

Start by defining the high-level conflict. This is usually a situation where you want an improvement, but something else prevents it.

  • Goal: "I want to increase the power of this engine."

  • Constraint: "But the engine becomes too heavy for the chassis."

2. Formulate the Technical Contradiction

Translate your real-world problem into the standard 39 Engineering Parameters defined by TRIZ. You must identify:

  1. The Improving Parameter: What are you trying to make better? (e.g., #9: Speed, or #3: Length of a moving object).

  2. The Worsening Parameter: What gets worse as a side effect? (e.g., #1: Weight of a moving object, or #31: Object-generated harmful factors).

3. Consult the TRIZ Contradiction Matrix

The Contradiction Matrix is a grid where the vertical axis represents the parameter to improve and the horizontal axis represents the parameter that worsens.

  • Locate the intersection of your two parameters.

  • The matrix will provide 3–4 numbers. These correspond to the specific Inventive Principles that have historically solved this exact type of conflict.

4. Analyze the Suggested Principles

Take the numbers from the matrix and look up the corresponding 40 Principles. For example, if the matrix suggests Principle 1 (Segmentation) and Principle 15 (Dynamicity):

  • Principle 1 (Segmentation): Can you divide the object into independent parts? (e.g., making a solid wing into a folding one).

  • Principle 15 (Dynamicity): Can you allow the object or its environment to change at each stage of operation? (e.g., using a flexible material instead of a rigid one).

5. Transition to a Practical Solution

This is the "Aha!" moment where you move from the abstract principle to a concrete engineering design.

  • Abstract: "Use Principle 10: Preliminary Action."

  • Concrete: "We will pre-heat the fuel using waste heat from the exhaust before it enters the combustion chamber to improve efficiency without adding a separate heater."

6. Evaluate Against First Principles

Once a solution is identified, verify that it doesn't violate fundamental laws of physics or create new, more complex contradictions. If the solution is still insufficient, you may need to apply Su-Field Analysis (Substance-Field) or the Ideal Final Result (IFR) concept to further refine the system.


Common PrinciplesBrief DescriptionExample
#1 SegmentationDivide into parts or make easy to disassemble.Modular furniture.
#10 Preliminary ActionPerform a change before it is needed.Self-adhesive stamps.
#13 'The Other Way Round'Invert the action or process.Moving the walkway instead of the person (escalator).
#28 Mechanics SubstitutionReplace a mechanical system with energy fields.Using magnetic levitation instead of ball bearings.

What pre-step is used to identify the contradictions?

The primary pre-step used to identify contradictions is Function Analysis (often paired with Root Cause Analysis or Cause-Effect Chain Analysis).

While the Contradiction Matrix is the "lookup table," you cannot use it effectively until you have mapped the system's functional relationships to find where the "harm" or "inefficiency" truly lives.

1. Function Analysis (The Component Map)

Before jumping to contradictions, you must decompose the system into its components and identify the functions (actions) they perform on each other.

  • Identify Components: List all parts of the system (substances and fields).

  • Define Interactions: For every two components, determine if the interaction is:

    • Useful: The system works as intended.

    • Insufficient: The function works but not well enough.

    • Harmful: The function creates a negative side effect.

    • Excessive: The function is stronger than necessary.

2. Cause-Effect Chain Analysis (CECA)

Once a "Harmful" or "Insufficient" function is found, you perform a deep dive to find the Root Contradiction. This involves asking "Why?" until you reach a fundamental conflict.

  • Example: A drill bit breaks (Harmful Function).

    • Why? The friction is too high.

    • Why? The rotation speed is high to maintain efficiency.

    • The Contradiction: High speed is needed for Productivity, but it causes Temperature/Friction which breaks the tool.

3. Formulating the "If-Then-But" Statement

The formal output of these pre-steps is a structured contradiction statement. This acts as the bridge to the 40 Principles:

IF we increase [Parameter A] to get [Benefit X], THEN [Benefit X] is achieved, BUT [Parameter B] becomes worse.

4. Defining the "Ideal Final Result" (IFR)

In more advanced TRIZ (like the ARIZ algorithm), you also define the IFR before looking for principles. You ask: "What would the system look like if it performed the function itself with zero cost or harm?" This helps ensure you aren't just making a minor trade-off, but are aiming for a breakthrough.


Summary of the "Pre-Step" Workflow:

  1. Map it: Use Function Analysis to find the specific component causing trouble.

  2. Trace it: Use CECA to find the underlying physical or technical reason for the trouble.

  3. Frame it: Write the If-Then-But statement using the 39 Engineering Parameters.

  4. Solve it: Take those parameters to the Contradiction Matrix.

Describe step-by-step TRIZ Functional Analysis

TRIZ Functional Analysis is a rigorous way to deconstruct a system to understand what it does rather than what it is. It moves the focus from objects to the actions between them, revealing the hidden inefficiencies and harmful effects that lead to technical contradictions.

Here is the step-by-step process for performing a formal Functional Analysis.


1. Define the System Boundary and Components

Identify everything involved in the specific problem. You must categorize these into two groups:

  • System Components: The parts you have control over or are trying to improve (e.g., a battery, a software module, a sensor).

  • Supersystem Components (Environment): External elements that interact with the system but cannot be changed (e.g., ambient temperature, the user, gravity, or a regulatory standard).

2. Identify the "Target" (The Product)

In TRIZ, every system exists to perform a function on a Product. The Product is the object that is being transformed, moved, or protected.

  • Example: If you are analyzing a cooling system, the "Product" is the Heat or the Component being cooled, not the fan itself.

3. Establish Functional Relationships

Draw a model where components are connected by arrows representing actions. A function must be expressed as a Subject + Action (Verb) + Object.

  • Subject: The component performing the action.

  • Action: The verb describing the modification of a parameter (e.g., heats, moves, holds, stabilizes).

  • Object: The component being acted upon.

4. Categorize Function Quality

This is the most critical step. For every interaction identified in Step 3, you must label the "Value" of the function using four specific categories:

  1. Useful (Standard): The function performs exactly as intended.

  2. Insufficient: The function is useful but doesn't meet the required performance level.

  3. Excessive: The function is useful but performs more than necessary (leading to waste).

  4. Harmful: The action creates a negative side effect or damages another component.

5. Build the Functional Model (Diagram)

Create a visual map using standard TRIZ notation:

  • Solid Line (—): Useful/Standard function.

  • Dashed Line (- -): Insufficient function.

  • Double/Bold Line (==): Excessive function.

  • Wavy Line (~~~): Harmful function.

6. Analyze and Identify the "Functional Bottleneck"

Look for clusters of wavy or dashed lines. These represent the "hot spots" of the system.

  • If you see a Harmful interaction, you have found your Technical Contradiction.

  • Example: If a "High-Speed Processor" (Subject) "Heats" (Action) the "Circuit Board" (Object) excessively, the contradiction is: Higher processing speed (Improving Parameter) causes higher thermal stress (Worsening Parameter).


Example: A Structural Support Beam

SubjectActionObjectStatus
BeamHoldsRoofUseful
BeamOccupiesSpaceExcessive
BeamConductsThermal EnergyHarmful (Heat loss)
Weight of BeamLoadsFoundationInsufficient (Too heavy)

7. Transition to Trimming (Optional but Recommended)

Once the model is complete, apply the Trimming rule: Can you remove a component and have its useful functions performed by another existing component or the supersystem? This often leads to the Ideal Final Result.

Would you like to apply this to a specific hardware or software architecture you are currently evaluating?


Describe step-by-step TRIZ Cause-Effect Chain Analysis (CECA)

While Functional Analysis maps the "space" of a system, Cause-Effect Chain Analysis (CECA) maps its "history." It is a surgical tool used to drill down from a surface-level problem to the underlying Key Contradictions and Key Problems.

Unlike a standard "5 Whys" approach, CECA is non-linear—it accounts for multiple causes leading to a single effect and branched consequences.


1. Define the Initial Disadvantage (Target Problem)

Identify the primary negative effect you are seeing in the system. This must be a specific, observable "harm" or "failure."

  • Example: "The FPGA cluster is overheating during high-density simulations."

2. Identify Immediate Causes

Ask: "What are the direct physical or technical reasons this disadvantage occurs?" List all possible causes. In TRIZ, these are often categorized as:

  • Substance-related: Materials, components, or chemicals.

  • Field-related: Energy, forces, heat, or magnetic fields.

  • Time/Space-related: Timing of events or physical layout.

3. Build the Chain (The Logical Flow)

Connect the Initial Disadvantage to its causes using "If-Then" logic.

  • Initial Disadvantage: FPGA Overheating.

  • Cause A: High power consumption of the gates.

  • Cause B: Insufficient airflow between the stacked boards.

  • Cause C: Thermal conductivity of the casing is too low.

4. Search for "Key Problems" and "Key Contradictions"

As you continue asking "Why?" for each cause, you will eventually hit two types of nodes:

  1. Key Problem: A cause that, if removed, eliminates several downstream disadvantages.

  2. Key Contradiction: A point where a cause is necessary for a useful function but simultaneously creates a disadvantage.

    • Example: "We need a high clock speed for Simulation Accuracy (Useful), but high clock speed causes Thermal Runaway (Harmful)."

5. Categorize the Nodes

In a formal CECA diagram, nodes are typically labeled to help prioritize the solution:

  • (+) Useful Effect: An action we want to keep.

  • (-) Harmful Effect: An action we want to eliminate.

  • Target: The node we choose to attack with the 40 Principles.

6. Pruning and Selection

Once the map is complete, you don't try to solve every node. You look for the "bottleneck" node—the one that sits at the intersection of the most branches.

  • The Trimming Trigger: If a component appears in multiple harmful chains, it is a prime candidate for "Trimming" (removing the component and redistributing its useful functions).

The "CECA to Matrix" Bridge

The final step of CECA is translating your "Key Contradiction" into the 39 Engineering Parameters.

  • Parameter to Improve: The useful reason the cause exists (e.g., #9: Speed).

  • Parameter to Prevent: The harmful result the cause creates (e.g., #31: Object-generated harmful factors/Heat).

This bridge allows you to take a complex, multi-branched failure and reduce it to a specific contradiction that the Matrix can solve.

Are you looking to trace a specific failure in a hardware architecture, such as a thermal or timing issue in a multi-board cluster?


Describe step-by-step how to Frame it with If-Then-But statements using the 39 Engineering Parameters

Framing the contradiction is the bridge between your raw engineering problem and the abstract world of TRIZ. This step converts a messy real-world issue into a standardized logical format that the Contradiction Matrix can understand.

Here is the step-by-step process to frame your problem using the If-Then-But structure and the 39 Engineering Parameters.


1. Identify the "Action" (The Change)

First, define the specific change you want to make to the system. This is usually the "knob" you are turning to improve performance.

  • Example: "I want to increase the clock frequency of my processor cluster."

2. Map the "Benefit" (The Improving Parameter)

Look at the 39 Engineering Parameters list. Which parameter describes the benefit you gain from that action? This is your Improving Parameter.

  • Action: Increase frequency.

  • TRIZ Parameter: #9 Speed (The rate of a process or the frequency of an action).

  • The "If-Then" part: "IF I increase the clock frequency, THEN the Speed (#9) is improved."

3. Identify the "Trade-off" (The Worsening Parameter)

Now, define the negative side effect that occurs when you perform that action. Scan the 39 Parameters again to find the one that best describes what "gets worse." This is your Worsening Parameter.

  • Side Effect: The power consumption spikes and generates too much heat.

  • TRIZ Parameter: #22 Loss of Energy or #31 Object-Generated Harmful Factors (Heat). Let's go with #31 for a physical system conflict.

  • The "But" part: "BUT the Object-Generated Harmful Factors (#31) becomes worse."

4. Construct the Formal "If-Then-But" Statement

Combine these into a single, rigid sentence. This forces you to acknowledge that you aren't just looking for a "tweak," but solving a fundamental conflict.

IF [I take Action X],

THEN [Improving Parameter #] is improved,

BUT [Worsening Parameter #] becomes worse.

Example Application:

  • IF I increase the number of FPGA nodes in the cluster,

  • THEN #10 Force/Power (Processing capability) is improved,

  • BUT #35 Adaptability/Versatility (System complexity/Difficulty to manage) becomes worse.


5. Validate the Contradiction

Before moving to the matrix, check your statement against these two criteria:

  1. Is it a true conflict? If you can solve it by just buying a bigger fan or spending more money, it’s an optimization problem, not a TRIZ contradiction. A TRIZ contradiction implies that the very thing that helps you is the thing that hurts you.

  2. Are the parameters precise? Don't settle for "Complexity" if "Reliability (#27)" or "Weight of a stationary object (#2)" is the more accurate physical description of the worsening factor.

6. The Matrix Lookup

Now that you have your two numbers, you are ready for the final step:

  • Vertical Axis (Y): Improving Parameter.

  • Horizontal Axis (X): Worsening Parameter.

  • The Intersection: Provides the 2–4 Inventive Principles (from the 40 Principles list) that are mathematically most likely to solve that specific conflict.


Common 39 Parameter Reference (Abridged)

#Parameter#Parameter
1Weight of moving object17Temperature
9Speed27Reliability
13Stability of object's composition31Harmful factors (Object-generated)
15Durability of moving object35Adaptability or Versatility

Would you like to try framing a contradiction for one of your current projects—perhaps regarding the communication latency or thermal load in your 1024-qubit emulator?


Describe step-by-step application of the TRIZ Contradiction Matrix

Once you have framed your problem as a formal If-Then-But statement using the 39 Engineering Parameters, the Contradiction Matrix acts as your navigational chart to find the most likely solutions.

Here is the step-by-step application of the Matrix.


1. Prepare Your Coordinates

You must have two specific numbers from the 39 Engineering Parameters list:

  • The Y-Axis (Vertical): The Improving Parameter. This is the feature you are trying to enhance (e.g., #9: Speed).

  • The X-Axis (Horizontal): The Worsening Parameter. This is the negative side effect that occurs when you try to improve the first parameter (e.g., #31: Object-generated harmful factors).

2. Locate the Intersection

The Matrix is a $39 \times 39$ grid.

  • Find your Improving Parameter in the far-left column (rows).

  • Find your Worsening Parameter in the top header (columns).

  • Follow the row and column until they meet at a specific cell.

3. Retrieve the Inventive Principles

Inside the intersection cell, you will typically find 2 to 4 numbers. These numbers refer to the 40 Inventive Principles.

  • Note: If a cell is empty, it means no historical solution was frequently found for that specific pairing. In this case, TRIZ experts recommend looking at the parameters immediately adjacent or using the "General TRIZ Principles" (like #1, #10, #13, #28).

4. Decode the Principles

Cross-reference the numbers from the cell with the list of the 40 Inventive Principles. For each principle, identify its core conceptual suggestion.

  • Example: If the cell contains 1, 15, 35, you look up:

    • #1: Segmentation (Divide the system into independent parts).

    • #15: Dynamicity (Make parts adjustable or movable).

    • #35: Parameter Change (Change the physical state, concentration, or flexibility).

5. Ideate Concrete Solutions

This is the most creative step. You must interpret the abstract principle through the lens of your specific technical domain (e.g., software architecture, FPGA routing, or mechanical design).

  • The "Analogy" Method: Ask, "How could Principle #15 (Dynamicity) solve my specific thermal issue?" * Result: "Perhaps I can implement dynamic frequency scaling that shifts workloads between FPGA boards based on real-time temperature sensors."

6. Verify and Select

Evaluate the ideas generated from the principles. A "good" TRIZ solution should:

  • Resolve the contradiction without a compromise.

  • Move the system closer to the Ideal Final Result (doing more with less).

  • Be technically feasible within your current constraints (budget, space, physics).


Summary of the Matrix Workflow

StepComponentAction
1InputIdentify Parameter A (Improving) and Parameter B (Worsening).
2MappingLocate Row A and Column B on the 39 x 39 grid.
3OutputExtract the 1–4 Principles suggested in the cell.
4TranslationConvert the abstract Principle into a specific engineering design.

Pro-Tip: The "Symmetry" Check

If you are struggling to find a solution, try swapping your parameters. Sometimes looking at the problem from the perspective of "I want to reduce the Harmful Factor (#31), but it lowers my Speed (#9)" reveals a different set of Inventive Principles that spark a better "Aha!" moment.

Are you ready to run a specific pair of parameters through the Matrix for your current system architecture?
